How do you work out how safe or dangerous a chemical or some other substance is? This week's Risk Bites takes a look at chemical safety, and estimating health risk from chemical exposure. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stuff) Risk Bite
How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How

The three types of a chemical reaction (analysis, synthesis and conversion) are only presented theoretically! An application and chemical experiments for this take place in the attendance phase at school! Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done b
In the 1950s, psychologist Solomon Asch developed a study to investigate whether peer pressure can be strong enough to change our perception and make us believe in things that are not true. To this end, he set up a clever experiment on conformity that raises questions about our ability to think free
Chemists always distinguish between the macroscopic and microscopic level. What does that mean? In the experiment zinc reacts with sulphur, this level is attempted to be demonstrated. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

In 1980, Benjamin Libet wanted to find out whether our brains were preparing for movement before we were aware of it. He set up an experiment to monitor brain activity and found that our brain becomes active 500 milliseconds before the conscious decision to move. What does this say about free will?
Have you ever felt that your past experiences have negatively affected your current state of being? Your childhood plays a major role in shaping the person you become as you grow older.
